So the greatest common factor 68,45,177 is 1.
Lets's calculate LCM of 219,434,393
3 | 219, 434, 393 |
73, 434, 131 |
∴ So the LCM of the given numbers is 3 x 73 x 434 x 131 = 12451026
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/12451026
Therefore, the GCF of Fractions 68/219,45/434,177/393 is 1/12451026
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 219,434,393 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(219,434,393) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(219,434,393) x common factors =1 x 3 = 3
LCM(219,434,393) = ( 219 × 434 × 393 ) / 3
LCM(219,434,393) = 37353078 / 3
LCM(219,434,393) = 12451026
